Abstract


With the rapid development of mobile Internet technology and the growing popularity of mobile terminals, personal mobile terminal is producing a large number of users' personal data, including photos, e-mail, text messages, calendar entries, contacts, and so on. With the continuous growth of the personal data, the retrieval needs of the users of these data have become increasingly prominent. Kaleido Photo is a mobile terminal on the user's personal information retrieval system, the use of full-text retrieval technology, personal data retrieval on mobile terminals. The system to retrieve photos entrance support the mark shared between the relevant photos and extended, and relevant information as to the photo retrieval conditions related event of the user's personal information retrieval. Semantic search subsystem as part of Kaleido Photo semantic search system, to provide users with a convenient keyword-based query to the personal data ontology-based semantic query. Semantic search subsystem also provides the user with a session-based SMS semantic organization programs, user-friendly in the view of SMS easily recall the time situational. The paper first introduces Kaleido Photo technology, including information retrieval technology, semantic desktop technologies, clustering technology, semantic query construction technology; goes on to describe the functional requirements of the system, as well as the system's hardware and software environment; then the demand Based on the analysis, the proposed design of the overall architecture of the system, and describes the overall design of the system module; then details the design and realization of the semantic search subsystem module. The focus of the paper is to discuss the Kaleido Photo semantic search subsystem design and the realization of the main modules. The paper details the data extraction module, semantic data storage module, semantic query automatically building blocks, the Semantic Query module as well as the SMS session clustering module design and implementation methods, and focus on the semantic query automatically construct algorithms and SMS session clustering Design and Implementation of the algorithm. Unit testing and integration testing system according to the needs and design programs to verify the functionality of the system, the functionality and performance of the system to achieve the design requirements. Finally, make a summary of the full text description of the existing deficiencies and possible further work, and summed up my graduate during the work and achievements.
